      Lacking petroleum, Germany must procure liquid fuels for future transport development largely from coal.  Liquid fuels by carbonization can be increased by (a) mild refining of coke-oven light oils; (b) use of the roof-canal and the Still process for protecting coke-oven light oils from decomposition; (c) further development of low-temperature carbonization.  Hydrogenation and synthesis from water gas will become important sources of liquid fuels.  Some progress has been made in the adaptation of the diesel motor to tar oils by use of a special fuel injector.
